Helicobacter pylori is the main risk-factor for gastric cancer through a cascade from gastritis through atrophic gastritis (AG), intestinal metaplasia (IM), dysplasia (DYS) to malignancy. The presence of these lesions in the general population predicts the gastric cancer incidence in the coming decades. Prevalence data are mostly obtained from serological studies and endoscopy data in symptomatic patients.


To investigate the prevalence of H. pylori infection and its related gastric changes in asymptomatic subjects.


383 Patients undergoing routine colonoscopy were included. All subjects underwent upper GI endoscopy and completed the Gastrointestinal Symptom Rating Scale (GSRS). Biopsies were taken from antrum and corpus.


H. pylori infection was present in 22%. Non-Caucasian subjects had a significantly higher H. pylori prevalence (p < 0.001). AG, IM and DYS were together found in 9.3% of subjects. Subjects with AG, IM or DYS were significantly older (p < 0.001). No differences were found with respect to gender, presence of GI symptoms as scored by GSRS, lifestyle and medication use.


The prevalence of premalignant gastric lesions is considerable in general Western population with increasing age as the main risk factor. One time screening for premalignant lesions at the age of 60 years is a reasonable strategy since the numbers found imply that gastric cancer will remain a prevalent disease.
